Sharpness and bokeh comparison of Nikon 50mm f/1.2, f/1.4G and f/1.8G

The contestants are Nikon 50mm f/1.2, f/1.4G and f/1.8G. The list prices are 38,550 INR, 27,990 INR and 18,000 INR respectively.

Bokeh: As with any portrait lens, I want a creamy bokeh performance when used wide open. Theoretically, as the maximum aperture increases, the bokeh effect should be more pronounced, too, if used wide open. But, how about the quality of bokeh? Is the difference at all perceivable in bare eyes? While searching for the image produced by all three lenses, I couldn't find any comparative review putting the shots taken by these lenses, side by side.

Sharpness: How do these three lenses perform in producing sharp images when used wide open? According to this review, f/1.4G performs worse than f/1.8G at least till f/5.6.
